A circular pencil case was made. The box has a diameter of 90mm and a height of 100mm. On the outer sides of this box, a regular pattern made up of five silhouettes of the American multipurpose fighter plane F-16, which extends over the entire circumference of the cup itself. The edges are rounded so that the user does not get hurt or cut on sharp edges. The model was made in SolidWorks and exported as an STL file. This box is intended to be made on a Bambu Lab P1S 3D printer with a 0.4mm nozzle.
